Last article I had seen mentioning Hewitt Lake said it would be Cascade Lake-based, but if Intel has 10nm Xeon D ready to go, I'd be surprised if they bothered releasing it. They already have Skylake Xeon D.
Could just be like the rest of the Icelake lineup, where it's being covered by 14 nm products.

Close to MX150 performance which is kinda bad I guess unless it's a 15W part.

It could be seen as bad, only thing is sisoft and its as synthetic of a test as it can be, so the truth is we still don't know.

Until it launches no one knows. Leaks are only for specs, but when do we get to know how the specs perform? On release date!

Nice find @Dayman1225 for Gen 11. Improvements everywhere.

The Linley paper mentions that Gen 11 forgoes DP FP capability and reduces Int ops performance in half. Likely the reason why it reduces size by 25% at same process. Gen 9 has 1/4 DP FP. It doesn't matter though.

Gen 9 reduces EU size over Gen 8 by 16% eliminating the ability to use both AoS and SoA models to just SoA.

Gen 11 likely uses immediate mode tiling similar to AMD and Nvidia rather than deferred mode.

The original Extreme Graphics, the second generation, and the GMA 9xx series used immediate mode tiling. They gave it up starting with the programmable shader based GMA X3000.

So really we've come full circle.

The loss of tiling, cutting down ROPs by half to 2, and very weak geometry engine is what caused the X3000 series to be often slower than the GMA 950 despite the former supporting full DX9 and programmable shaders.

Iris Pro Graphics 950/40/30 and UHD Graphics 920/10, all GT2 configuration.
The 32/48/64 numbers at the end seem to indicate how many EUs it has however. They can always change the branding name later I guess, since it doesn't seem right to have GPUs with the same name and different EU counts.

Wonder what GT0.5 means... maybe no EUs activated or only like 8?

Good eye, just notice Iris Plus 950 is 64EUs and 25w? Assuming that’s right

The Gen 11 whitepaper has interesting detail about the tile rendering its using.

It's entirely theirs, considering searching for it shows a patent dating back to 2015.

So Intel has a Data Centric Innovation day on the second of April where Cascade Lake will almost certainly be launched

I know this isn’t entirely relevant to this thread but I don’t think Cascade Lake needs a new thread created for it as it’s more or less Skylake SP refreshed with Optane DIMMs, AVX512 VNNI and Smeltdown security mitigation’s. Though I doubt Cascade Lake will be the only thing presented.
